5.1 Lighting Modes
The fixture offers 5 smart lighting modes:
- DIM Mode: At night, the light maintains 40% brightness. Upon motion detection, it switches to 100% brightness and reverts to 40% when motion ceases.
- ECO+ Mode: The light remains off at night. It activates to 100% brightness upon motion detection and turns off completely when motion ceases.
- D2D Mode (Dusk-to-Dawn): The light automatically turns on at 100% brightness at dusk and turns off at dawn.
- Override Mode: Maintains 100% brightness for 8 hours at night. It turns off at dawn and automatically returns to the previously selected AUTO mode.
- ON Mode: Maintains 100% brightness throughout the day and night.
